The Modeling and Simulation Research Group focuses on constructing computer-based mathematical, graphical, and algorithmic representations of real-world systems and phenomena while evaluating their realism and accuracy. Established in 2009, the group has been actively engaged in research, development, and commercialization, contributing significantly to various industries and national development.

Our expertise lies in Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) solutions, which have been successfully implemented in organizations such as the Sri Lanka Navy, Sri Lanka Army, Sri Lanka Air Force, Sri Lanka Port Authority, Ministry of Fisheries, and Ocean University. Notable projects include: Vidusayoura – A ship-handling simulator, Siyara VTMS -A 3D vessel traffic monitoring system and Field Artillery Simulation System – A military training simulation.

In addition to these, this research group has made numerous national contributions, delivering cutting-edge technological solutions. Since its inception, the group has won prestigious awards, including the e-Swabhimani Award, Asia Pacific ICT Alliance (APICTA) Awards, and NBQSA (National Best Quality Software) Awards. Our research output includes over 100 publications, spanning book chapters, journal articles, conference proceedings, and newsletters. Furthermore, we have secured national and international research grants from various donor agencies.

Building on our extensive experience, the Modeling and Simulation Research Group is now expanding its frontiers into sports biomechanics through modeling, simulation, analysis and visualizations.

Vidusayura Ship Handling Simulator

The most effective solution for the ship handling training is the use of a ship simulator. Unfortunately, such simulators are extremely costly. To remedy this situation University of Colombo School of Computing (UCSC) started to develop a ship handling simulator, named ViduSayura. The salient feature of ViduSayura is that is entirely developed using the Commodity Off the Shelf hardware and open source software. Therefore ViduSayura is extremely cost effective and it also frees the users from getting locked into a vendor specific proprietary solution.Currently, Vidusayura is funded by National research council Sri Lanka.

ICT based home-grown Vessel Traffic Monitoring solution for the Colombo Port

His Excellency the President Mahinda Rajapaksa formally declared open the newly-expanded Colombo South harbor of the Colombo Port including its new Control Tower/Pilot station, Colombo International Container Terminals Ltd (first stage)  for business on  5th August 2013.  It will allow Sri Lanka to regain its role as a leading South Asia trans-shipment hub. The 56 meter high new Control Tower/Pilot station operates with the support of a home-grown Vessel Traffic Monitoring System (VTMS) which is developed as a project of the modeling and simulation group of the University of Colombo School of Computing.
